两次之间的时间间隔计算器

Question

<input type = "text" name = "time1" value = "<?php echo $row['Hours']; ?>"> 
<input type = "text" name = "time2"> 
<input type = "submit"name = "Compute" value = "Compute" > 

$calc=""; 
if(isset($_POST["Compute"])) 
{ 
$time1=$_POST['time1']; 
$time2=$_POST['time2']; 


$calc = ($time1=$_POST['time1']-$time2=$_POST['time2']); 

我想计算两次之间经过的时间。例如，我在TextBox1中输入上午9:30，然后在TextBox2中我进入下午5:00

Answer 1

使用strtotime功能

(strtotime('12:45:00') - strtotime('11:00:00'))/60
